To all whom it 'may concern; c

Be it known that I, GoTTLrEB H. SIMON, a citizen of the United States,residing at Kiel, county of Manito woc and State of Wisconsin, h'aveinvented new and useful Improvements in Milk-Vats, of which thefollowing is a specification.

My invention relates to improvements in sheet metal milk vats and itpertains to that class which is used for heating milk in the process ofmaking cheese.v

The construction oi my invention is explained by reference to theaccompanying drawings in which,

Figure l is a bottom view. Fig. 2 is a vertical transverse section drawnon line xx of Fig. l. Fig. 3 is adetail showing an enlarged view of theseams and strengthening flanges together with the reinforcing plateswhich are used to strengthen the bottom of the vat at the junction ofthe longitudinal transverse seams formed in the bottom of the vat. Figs.4 and 5 are details. i

Like parts are identified by the same reference characters throughoutthe several views.

The vat comprises the side pieces l, end pieces 2 and the bottom 3, andsuch parts are constructed of a plurality of sections oi sheet metal 4.The number of such pieces or sections vary of course according to thesize of the vat or sections of sheet metal. The several sections oisheetmetal have their contiguous edges bent outwardly at right angles totheir central portions and secured together in such a manner as to formseams and strengthening flanges. It will be understood that these vatsare subject to great pressure and strain amounting to several tons. Forthis reason the seams oi the several sections of the vat must be ofgreat strength. That the seams may have the required strength theopposing edges of the sections both at the bottom and sides are made ofdouble thickness by folding the edges back upon themselves as indicatedin Figs. 2 and 3 at substantially right angles to their central portionsand such parts being bent as shown between points A B and B O.

As additional means of adding strength to the structure, I preferablyinsert an additional sheet metal plate or disk E between the opposingsurface oi the seams when the upper edge of the disk' is bent over uponthe bottom 3 of the vat, while the lower portion of the disk is bentupwardly in a U shape in the opposite direction beneath the opposingsection of the bottom as shown in Figs. 2 and 3, when the seams andjoints thus formed are securely soldered together.

It will be understood that the upper edge oi the disk E is bent at rightangles parallel to the bottom of the vat above the transverse seams H asindicated in dotted lines in Fig. l, and as clearly shown in Figs. 2 and3, while the lower edgmf said disk E is bent in the opposite directionaround-tile longitudinal seam I of the vat.

Heretofore it has been common to form the transverse seams upon one sideof the longitudinal center of the vat in line with those upon theopposite side of the vat. By the construction shown, however, thetransverse seams H upon one side of the longitudinal center terminatemidway of the opposing section of the metal upon theopposite side ofsuch longitudinal center, whereby a Istrain that would otherwise have atendency to separate the sections at the junction of said seams when allof said seams unite at a common center is divided and more uniformlydistributed and the sections are less liable to be torn asunder by thepressure against it.

In practical use two vats of similar construction are preferably usedtogether as shown in Fig. 2 in which case the exterior vat is madelarger and supported from a rectangular frame 5 by the supporting leg 6,when the smaller vat is supported from and within thelarger vat. Themilk to be heated is placed in the interior vat and is usually heated byhot water located in the exterior vat, the seams of the respective vatsbeing formed in like manner.

To give additional strength to the seams and strengthening iianges H atthe corners H of the vat, I preferably provide such iianges with aninclosing cap I0, which is formed oi a piece of flexible sheet metal andbent to conform to the said vertical and side portions of the flange asshown in Figs. 4.- and 5 when such caps are secured in place by solderin `the usual manner.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is,

l. In a milk "vat of the described class the combination of a pluralityof sections of sheet metal having; theiricontiguous edges respectivelybent outwardly at right angles to their central portions and folded backupon themselves so as4 to perform the two-fold function of s eams andstrengthening iianges and means of securing said folded edges together,substantially as set forth.

2. In a milk vat of the described class the combination of a pluralityof sections of sheet metal having their contiguous edges respectivelybent outwardly at right angles to their central portions and folded backupon themselves so as to perform the twofold function of seams andstrengthening flanges and means of securing said folded upon one side ofthe longitudinal center of the vat being seams upon the opposite side ofsuch longitudinal center, substantially as set forth.

3. In a milk vat of the described class the combination of a pluralityof sections of sheet metal having their conunited with the longitudinalseam between the transverse' edges together, the transverse seamsbetween the sections tguous edges respectively bent outwardly at rightangles to their central portions and folded back upon themselves so asto perform the two-fold function of seams and strengthening ang'es, areinforcing disk located at the 5 junction of said longitudinal andtransverse seams, the upper edge of said reinforcing disk being bent atright angles parallel to the bottom of the vat above the transverseseam, While the lower edge of said reinforcing disk is folded in theopposite direction beneath and around said longitudinal seam, and meansfor securing said seams 10 and reinforcing disk together, allsubstantially as and for the purpose specified.

In testimony whereof I affix my signature in the presence of twowitnesses.
